| endocarditis | <pathology> Exudative and proliferative inflammatory alterations of the endocardium, characterised by the presence of vegetations on the surface of the endocardium or in the endocardium itself and most commonly involving a heart valve, but sometimes affecting the inner lining of the cardiac chambers or the endocardium elsewhere. It may occur as a primary disorder or as a complication of or in association with another disease. (18 Nov 1997) |
|---|---|
| endocarditis chordalis | Endocarditis affecting particularly the chordae tendineae. (05 Mar 2000) |
| Libman-Sacks endocarditis | Verrucous endocarditis sometimes associated with disseminated lupus erythematosus. Synonym: atypical verrucous endocarditis, Libman-Sacks syndrome, nonbacterial verrucous endocarditis. (05 Mar 2000) |
| Loffler's endocarditis | Fibroplastic parietal endocarditis with eosinophilia, an endocarditis of obscure cause characterised by progressive congestive heart failure, multiple systemic emboli, and eosinophilia. Synonym: Loffler's disease, Loffler's syndrome. (05 Mar 2000) |
| Loffler's parietal fibroplastic endocarditis | Sclerosis of the endocardium in the presence of a high eosinophile count. (05 Mar 2000) |
| adhesins, bacterial | Cell-surface components or appendages of bacteria that facilitate adhesion (bacterial adhesion) to other cells or to inanimate surfaces. most fimbriae (fimbriae, bacterial) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. (12 Dec 1998) |
| antibodies, bacterial | Immunoglobulins induced by substances elaborated by bacteria that have an antigenic activity. (12 Dec 1998) |
| antigens, bacterial | Substances elaborated by bacteria that have antigenic activity. (12 Dec 1998) |
| atypical bacterial forms | Microorganisms that have undergone greater changes than normal in morphology, physiology, or cultural characteristics. (12 Dec 1998) |
| bacterial | <microbiology> Bacteria are group of micro-organisms that are a single cell approximately 1 micron in transverse diameter. Some bacteria cause disease in man, requiring treatment with an antibiotic. (27 Sep 1997) |
| bacterial adhesion | Physicochemical property of fimbriated (fimbriae, bacterial) and non-fimbriated bacteria of attaching to cells, tissue, and nonbiological surfaces. It is a factor in bacterial colonization and pathogenicity. (12 Dec 1998) |
| bacterial allergy | The concept that the atopic kind of type I allergic reactions may be caused by bacterial allergens, the delayed type of skin test, so-called because of its early association with bacterial antigens (e.g., the tuberculin test). (05 Mar 2000) |
| bacterial antagonism | The inhibition of one bacterium by products of another. (05 Mar 2000) |
| bacterial capsule | A layer of slime of variable composition which covers the surface of some bacteria; capsulated cells of pathogenic bacteria are usually more virulent than cells without capsules because the former are more resistant to phagocytic action. (05 Mar 2000) |
| bacterial capsules | An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.
